17328db3b3 grub-core/kern/arm/misc.S: fix unaligned grub_uint64_t local variable 
The unaligned local in __aeabi_uidivmod leads to a store to a 64bit
value at an address that is not divisible by 8 (in grub_divmod64).
The compiler most likely generates a STRD instruction to store it and
this causes an exception.

Fixes Savannah bug #43632.

This includes improvements done by Leif Lindholm.

004a2b1efd efi: check *path non-null before grub_strrchr 
The EFI version of grub_machine_get_bootlocation crops the boot image
name back to the last / in order to get a directory path. However, it
does not check that *name is actually set before calling grub_strrchr
to do this, and neither does grub_strrchr before dereferencing a NULL
pointer.

Parent function, grub_set_prefix_and_root, does check the pointer
before using.

2a5a532c00 Support grub-emu on x32 (ILP32 but with x86-64 instruction set) 
* configure.ac: Remove -m64 from checks for -mcmodel=large and
-mno-red-zone.  These are always either unnecessary (x86_64-emu) or
already in TARGET_CFLAGS at this point, and they produce incorrect
results when building for x32.
* grub-core/kern/x86_64/dl.c (grub_arch_dl_relocate_symbols): Cast
pointers to Elf64_Xword via grub_addr_t, in order to work on x32.
* include/grub/x86_64/types.h (GRUB_TARGET_SIZEOF_VOID_P,
GRUB_TARGET_SIZEOF_LONG): Define to 4 on x32.

e4a1fe3919 ieee1275: check for IBM pseries emulated machine 
is_qemu is not being set lead to disabling of feature like
GRUB_IEEE1275_FLAG_HAS_CURSORONOFF. This resulted in cursor not being
displayed during the grub-menu edit.
